Cold pressing and refining method of camellia oil

Abstract

The invention discloses a cold pressing and refining method of camellia oil. The cold pressing and refining method comprises the following operation steps: separating camellia seed kernels from camellia seed husks of camellia seeds, rolling into a material blank, further performing steaming, stir-frying and drying, and then feeding the material blank into a cold pressing machine for pressing; and further performing degumming, alkaline refining, washing with water, decolorization, deodorization and dewaxing to obtain finished camellia seed oil. The quality of the camellia oil processed by adopting the method in various items is better than that of hot pressed oil; furthermore, the camellia seed oil produced by the method disclosed by the invention has soft and fine taste and crystal and bright luster, and can be used for direct eating and cold mixing; a camellia seed oil product produced by the method has more stable quality in comparison with the prior art; tests prove that the benzopyrene content in the product can not be detected, the decoration effect is excellent, and the cake residual oil is reduced from original 10-12% to 7-9%.

Description

Technical field [0001] The invention relates to a method for cold pressing and refining camellia oil. Background technique [0002] Camellia oil is derived from the mature seeds of Camellia oleifera or Camellia oleifera, that is, camellia seeds, and the fatty oil is obtained by squeezing, leaching and other methods. Camellia seed oil is a pure natural high-grade woody edible oil with good quality and natural health. It is a treasure in the oil. It is one of the oldest woody edible vegetable oils in my country and one of the four largest woody vegetable oils in the world. [0003] Cold pressed camellia oil is used to squeeze vegetable oil under the condition of low temperature, and it is called cold pressing because the processed tea oil seeds are not steamed and fried in the traditional hot pressing process, and the oil in the raw material is still distributed In the undeformed protein cells, the cold-pressed camellia oil retains a lot of the inherent components in the camellia oi...

Problems solved by technology

[0004] However, the oil yield of the existing cold-pressed camellia oil process is relatively low

[0005] Hot-pressed camellia oil refers to the vegetable oil obtained by physical pressing of camellia oil seeds after high-temperature frying or steaming. It is a traditional oil-making process; Benzopyrene and other harmful properties that are harmful to the human body, and because the high temperature time is too long, a large amount of pigment substances will be produced during this high temperature process, making the oil color too dark and the taste bitter. Since the entire production process is in a high temperature state, The rich nutrients in Camellia oleifera oil have been greatly damaged
